Figure 17.Comparison of zooplankton collected (dotted line) from Old Charley Wash in the spring and summer between 1994 and 1996
with river discharge (light solid line) measured in Jensen and the duration of larval razorback sucker collected in the middle Green River
(heavy horizontal line). The larval razorback duration line is located at the 447 cms scale to compare larval presence with floodplain
connection, and the flows in which most backwaters appear (109 cms) is noted with an arrowhead.
